With Packstack, WSGI is still supported.  With Tripleo, you need the 
absolute latest out of upstream, as the first take of Tripleo put 
Keystone in Eventlet, and getting it out of there required careful work 
by people much better at puppet than I  am (Hi Emilien).

Sorry about that. But I am now testing Tripleo Federation and it seems 
to be OK.  The biggest thing is to avoid touching the Puppet managed 
files, and to make your changes in separate files, so that a redeploy 
does not overwrite your changes.
